By mixing the aerosols obtained by atomizing the heating atomizer and the ultrasonic atomizer, a mixed flavor can be achieved. In a commonly used ultrasonic atomizer, generally, an internal ultrasonic atomization sheet is used to atomize an aerosol matrix to generate an aerosol. When the ultrasonic atomizer is working, the ultrasonic atomization sheet of the ultrasonic atomizer often atomizes at a fixed vibration frequency.

[0003] However, during operation, the actual vibration frequency of the ultrasonic atomizer is affected by the structure of the atomization sheet itself and will change with the increase in temperature. Therefore, the vibration frequency of the ultrasonic atomizer is affected, making it difficult to reach the required target vibration frequency. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. It should be noted that for the flow methods in this embodiment, the sequence of each step does not represent an inevitable execution sequence. For some steps without a causal relationship, they can be carried out synchronously or successively.

[0028] Please refer to Figure 1 , in an embodiment, the present application provides a control method for an atomization device. The atomization device is provided with at least one heating atomizer and at least one ultrasonic atomizer. The control method includes:

[0029] S10. Detect the real-time power of the heating atomizer;

[0030] S20. Calculate the difference between the real-time power and the preset power;

[0031] S30. Adjust the vibration frequency of the ultrasonic atomizer according to the difference;

[0032] Among them, the heating atomizer is configured to generate a first aerosol, and the ultrasonic atomizer is configured to generate a second aerosol.

[0033] In this embodiment, the atomization device is an atomization device capable of dual atomization. Among them, the heating atomizer heats the matrix to be atomized through its own atomization core to atomize it into aerosol. Therefore, the step of detecting power is to detect the power of the heating atomizer. Among them, the ultrasonic atomizer can also atomize the matrix into aerosol through the vibration of the ultrasonic atomization sheet. Therefore, by adaptively adjusting the ultrasonic frequency, the generation amount of aerosol in the ultrasonic atomizer can be adaptively adjusted, and then the taste can be adjusted.

[0034] In step S10 of this embodiment, to detect the real-time power of the heating atomizer, it can be to detect the real-time power through an existing detector, or to detect other operating parameters such as current, voltage, resistance, etc., and then calculate the real-time power of the heating atomizer, or it can be to obtain the rated real-time power of the heating atomizer itself.

[0035] In steps S20 and S30 of this embodiment, calculating the difference between the real-time power and the preset power is to calculate the distance between the current real-time power and the required real-time power, that is, the distance between the current vibration frequency and the target vibration frequency of the ultrasonic atomizer can be indirectly obtained. Therefore, adjusting the vibration frequency of the ultrasonic atomizer according to the difference can enable the ultrasonic atomizer to atomize at the required target vibration frequency to improve the use experience of the ultrasonic atomizer. That is, in this embodiment, the difference in step S20 is used to judge and adjust the vibration frequency in subsequent step S30.

[0036] In one example, the preset power is the optimal power of the heating atomizer obtained through experiments. In another example, the preset power is the maximum power of the heating atomizer. In the above examples, the preset power can be input and set before step S10, or can be input and set in step S20.

[0037] In step S30 of this embodiment, adjusting the vibration frequency of the ultrasonic atomizer according to the difference can be to calculate and analyze the vibration frequency under the preset power according to the difference, and then adjust the current vibration frequency to the vibration frequency under the preset power, and then lock the vibration frequency. It can also be to calculate the distance between the current vibration frequency and the target vibration frequency corresponding to the preset power according to the difference, and then gradually approach the target vibration frequency by steps with the current vibration frequency, and finally lock the vibration frequency. Among them, the vibration frequency is the vibration frequency of the ultrasonic atomization sheet in the ultrasonic atomizer.

[0038] Please refer to Figure 2 In another embodiment, steps S10 and S30 are optimized to provide a control method for an atomization device. Among them, step S10 includes steps S11, S12 and S13, and step S30 includes step S300, specifically:

[0039] S11, Detect the operating parameters of the heating atomizer;

[0040] S12, Filter the operating parameters through the Kalman filter algorithm;

[0041] S13, Calculate the real-time power based on the updated operating parameters;

[0042] S20, Calculate the difference between the real-time power and the preset power;

[0043] And / or, S300, Adjust the algorithm parameters of the Kalman filter algorithm and the vibration frequency of the ultrasonic atomizer according to the difference, or lock the vibration frequency of the ultrasonic atomizer according to the difference.

[0044] In this embodiment, first optimize the method for detecting the real-time power of the heating atomizer in step S10. In step S11 of this embodiment, detect the operating parameters of the heating atomizer and calculate the real-time power by calculating the operating parameters. At the same time, in step S12 of this embodiment, also filter the operating parameters through the Kalman filter algorithm. Through filtering, denoise the signal of the obtained operating parameters to remove the random interference mixed in the signal, make the signal clearer, be able to update the obtained operating parameters, improve the reliability and accuracy of the operating parameters, make the operating parameters used for calculation more accurate, and further improve the accuracy of the real-time power obtained in step S13. Specifically, in this embodiment, step S11 can be carried out through an ADC. ADC is the abbreviation of Analog-to-Digital Converter, which is mainly used to convert the continuously transmitted analog signal into a digital signal, facilitating the digital system such as the central processing unit CPU, microcontroller MCU, etc. to quickly process and analyze the transmitted information.

[0045] In this embodiment, the step can end after executing step S20, or continue to execute step S300 after executing step S20.

[0046] In this embodiment, continue to optimize step S30 to step S300. In step S300, adjust the vibration frequency of the ultrasonic atomizer according to the difference so that the vibration frequency of the ultrasonic atomizer reaches the required target vibration frequency, and can lock the frequency when it reaches, so as to improve the atomization efficiency of the ultrasonic atomizer and further improve the use experience of the atomization device.

[0047] In this embodiment, introduce the Kalman filter algorithm of step S12. In this embodiment, the Kalman filter algorithm includes two equations, which are specifically as follows:

[0048] 1. State equation (prediction equation) of the system:

[0049] x k = A k x k-1 + B k u k + w k

[0050] 2. Measurement equation:

[0051] z k = H k x k + v k

[0052] Where: A k is the state transition matrix; u k is the state control vector; B k is the control variable matrix; w k is the noise of the control system, which follows a Gaussian distribution: w k ~ N(0, Q); Q is the covariance matrix of the system noise; Z k is the measurement vector; H k is the conversion matrix from the state vector to the measurement vector; v k is the measurement noise, which follows a Gaussian distribution: v k ~ N(0, R); R is the covariance matrix of the measurement noise. In the Kalman filter algorithm, the important parameters include Q and R. Among them, Q is the process noise. The smaller Q is, the easier it is for the system to converge, indicating a higher confidence in the predicted values of the model; R is the measurement noise. The larger R is, the slower the response of the filter (here the response specifically refers to the response to the measured value) will be, that is, the larger R is, the slower the system converges and the lower the confidence in the new measured values. In this embodiment, step S13 may be to calculate the current and real-time power through the ADC value.

[0053] Taking an example, please refer to Figure 3 , step S11 is specifically: measuring the data of the atomization device system through the ADC and reading the ADC value of BAT3. Further, step S12 is specifically: using the Kalman filter algorithm to update the ADC value. The purpose of this setting is to reduce the influence of noise and improve the accuracy of subsequent calculations. Further, step S13 is specifically: calculating the current and real-time power of the system based on the filtered ADC value. That is, calculating the pressure difference between BAT+ and BAT3, where R is the resistance, the resistance value of R18 = 0.2R; BAT+ is the battery voltage; BAT3 is the ultrasonic working voltage; BAT_EN is the ultrasonic power supply enable; the calculation formula is as follows:

[0054] Ultrasonic current = (voltage of BAT+ - voltage of BAT3) / 0.2R;

[0055] Ultrasonic power = ultrasonic current * voltage of BAT3.

[0056] Continuing the introduction of the present application, during the process of adjusting the vibration frequency of the ultrasonic nebulizer, in order to adjust the vibration frequency of the ultrasonic nebulizer to reach the required target vibration frequency range or target vibration frequency value, it is necessary to perform frequency sweeping on the atomization range of the vibration frequency of the ultrasonic wave. The ordinary frequency sweeping method has low efficiency, and in practice, affected by the aerosol matrix to be atomized (including liquids such as e-liquid) itself and the structure of the atomization sheet itself (such as uneven pore size, etc.), it is difficult to lock the change frequency of the atomization sheet in the ultrasonic nebulizer. Furthermore, the ultrasonic nebulizer needs to perform frequency conversion multiple times to reach the required target vibration frequency, resulting in difficulties in determining and locking the vibration frequency. In response to this, the present application further optimizes the above process. For specific details, please refer to the following embodiments.

[0057] In this embodiment, step S300 includes two parts, step S300-A and step S300-B, that is:

[0058] S300-A, adjusting the algorithm parameters of the Kalman filter algorithm and the vibration frequency of the ultrasonic nebulizer according to the difference;

[0059] S300-B, locking the vibration frequency of the ultrasonic nebulizer according to the difference.

[0060] Next, step S300 will be optimized according to step S300-A and step S300-B respectively.

[0061] Please refer to Figure 2 and Figure 3 , in one embodiment, step S300 is further optimized to provide a control method for an atomization device. Among them, step S300 includes steps S301, S302, and S303, specifically:

[0062] S301, setting multiple preset differences, setting corresponding preset algorithm parameters and corresponding preset step values according to the preset differences;

[0063] S302, gradually judging the magnitude of the difference and each preset difference;

[0064] S303, according to the judgment result, updating the algorithm parameters to the corresponding preset algorithm parameters, stepping and adjusting the vibration frequency of the ultrasonic nebulizer with the preset step value, or locking the vibration frequency of the ultrasonic nebulizer as the first target frequency, so that the ultrasonic nebulizer operates at the first target frequency.

[0065] Among them, step S303 includes two parts, step S303-A and step S303-B, that is:

[0066] S303-A, update the algorithm parameters to the corresponding preset algorithm parameters, and stepwise adjust the vibration frequency of the ultrasonic nebulizer with a preset step value;

[0067] S303-B, lock the vibration frequency of the ultrasonic nebulizer as the first target frequency, so that the ultrasonic nebulizer operates at the first target frequency.

[0068] In this embodiment, steps S303-A and S303-B are further optimized steps of the above step S300 respectively.

[0069] Among them, setting multiple preset differences in step S301 does not limit the number of preset differences. Specifically, the number of preset differences set can be selected according to actual needs. It can be understood that the more the number of preset differences, the more intervals are divided, making the range of gradual judgment in step S302 more detailed.

[0070] In step S301 of this embodiment, first, the preset algorithm parameters are the calculation parameters of the above Kalman filter algorithm. In one embodiment, the preset algorithm parameters include Q and R. Secondly, the preset step value is set according to requirements and can make the vibration frequency gradually approach the target vibration frequency. Specifically, the magnitude of the preset step value is set according to the magnitude of the preset difference, that is, the absolute value of the preset step value increases as the absolute value of the preset difference increases. And the preset step value has positive and negative properties, that is, the preset step value can make the current vibration frequency adjust forward or backward to make it closer to the target vibration frequency. For example, when the current vibration frequency of the ultrasonic nebulizer is 150k and the target vibration frequency is 155k, the preset step value can be +5, so that the vibration frequency steps towards the target vibration frequency with +5. Another example, when the current vibration frequency of the ultrasonic nebulizer is 150k and the target vibration frequency is 145k, the preset step value can be -5, so that the vibration frequency steps towards the target vibration frequency with -5.

[0071] In step S302 of this embodiment, taking an example for illustration, the step-by-step judgment method includes: sorting multiple preset differences from large to small in sequence. When making a judgment, the differences are judged one by one with the preset differences in the order from large to small, and step S312 is executed accordingly. Under this setting, when judging the difference and the preset difference, since the judgment is made step by step from large to small, it is possible to classify or perform a distributed frequency sweep on the vibration frequency according to the distance between the vibration frequency and the target vibration frequency during the use of the ultrasonic nebulizer, improve the frequency sweep efficiency of the atomization range, and achieve classification or step-by-step frequency locking according to this distance. Under this setting, during the step-by-step judgment process, if one of the steps causes the vibration frequency to reach the target vibration frequency or reach the atomization range of the vibration frequency, the stepping of the vibration frequency can be stopped, thereby reducing the frequency conversion times of the ultrasonic nebulizer and improving the frequency sweep efficiency. Moreover, this setting can reduce the atomization fluctuation caused by the contact difference between the atomization sheet and the corresponding chamber during the rotation and switching of the chamber body during the actual atomization process. Therefore, through the above steps, the frequency sweep efficiency can be improved and the frequency conversion times can be reduced.

[0072] Taking another example for illustration, the step-by-step judgment method can also include: sorting multiple preset differences from small to large in sequence. When making a judgment, the differences are judged one by one with the preset differences in the order from small to large, and step S312 is executed accordingly. Compared with the above method of judging one by one from large to small, this setting can slow down the speed at which the vibration frequency approaches the target vibration frequency, thereby avoiding the occurrence of damage to the atomization sheet structure due to too fast frequency conversion and improving the service life of the atomization sheet.

[0073] In step S303 of this embodiment, different processing methods are executed according to the judgment result. Taking one embodiment for illustration, it can be to update the algorithm parameters to the corresponding preset algorithm parameters according to the judgment result. That is, the parameters in the above Kalman filter algorithm are updated to reduce the influence of noise and improve the accuracy of calculating subsequent parameters such as real-time power. At the same time, since the vibration frequency of the ultrasonic nebulizer changes relatively fast, by updating the parameters in the above Kalman filter algorithm, the sensitivity of the Kalman filter algorithm to the measured value is increased, so that the prediction can follow the change of the vibration frequency faster. In one embodiment, a Kalman filter is used to execute the Kalman filter algorithm.

[0074] Illustrated by another embodiment, the vibration frequency of the atomizer can be adjusted in preset step values according to the judgment result, that is, the scanning range of frequency sweeping is increased. As described in the above embodiment, the judgment result of the difference and the preset difference can reflect the distance between the vibration frequency and the target vibration frequency. Therefore, according to the judgment result, the vibration frequency is stepped in preset step values, so that the vibration frequency gradually approaches the target vibration frequency until it is equal to the target vibration frequency or within the range where the target frequency is located. At this time, frequency locking is performed, that is, the adjusted vibration frequency is output, so that the ultrasonic atomizer works at the adjusted vibration frequency to complete the adjustment.

[0075] Illustrated by yet another embodiment, the vibration frequency of the atomizer can be locked according to the judgment result and work at this vibration frequency. That is, during the judgment and adjustment process, the vibration frequency of the ultrasonic atomizer is already equal to the target vibration frequency or within the range of the target vibration frequency. At this time, frequency locking is directly performed, and the vibration frequency is used as the required target vibration frequency, that is, the first target frequency, and work is carried out at the first target frequency, thereby avoiding ineffective frequency conversion.

[0076] The first target frequency in this embodiment is described. The first target frequency in this embodiment is the target vibration frequency that needs to be achieved in this adjustment and frequency tracking. In fact, it is a preset value set according to actual needs. In one embodiment, the first target frequency is the optimal frequency of the ultrasonic atomizer. Specifically, after adjustment and frequency tracking, the vibration frequency of the ultrasonic atomizer will gradually approach the first target frequency, and the finally locked vibration frequency can be used as (i.e., regarded as) the first target frequency of the ultrasonic atomizer. The reason why the above explanation includes within the range of the target frequency is that in practice, the vibration frequency is affected by factors such as ambient temperature, atomization matrix, and the material and structure of the atomization sheet itself, resulting in the fact that the actual atomization sheet is difficult to track the frequency to be exactly equal to the preset first target frequency, but will fluctuate slightly around the first target frequency. However, through frequency tracking, the error between its vibration frequency and the preset value is already very small and can be ignored. Therefore, the first target frequency obtained by locking after the adjustment and frequency tracking in this application can be regarded as the initially preset first target frequency.

[0077] Next, some embodiments are continued to further illustrate the above steps in detail. In one embodiment, the above step S300 is further optimized by setting two judgments of preset differences. The step S300 includes steps S304, S305, S306, S307, S308, and S309. Among them, step S304 is a further optimized step of step S301; steps S305 and S307 are further optimized steps of step S302; steps S306, S308, and S309 are further optimized steps of step S303, and the specific content is as follows:

[0083] S309, lock the vibration frequency of the ultrasonic nebulizer as the first target frequency, so that the ultrasonic nebulizer works at the first target frequency.

[0084] In this embodiment, the first preset difference is set between 0.4 - 1.5 W, and the second preset difference is set between 0.1 - 0.3 W; the first preset algorithm parameter is Q ∈ [0.08, 0.7], R ∈ [0.5, 10], and the third preset algorithm parameter is Q ∈ [0.01, 0.07], R ∈ [15, 30], where Q is the process noise and R is the measurement noise; the first preset step value is between ±6 - 12 kHz, and the second preset step value is between ±2 - 5 kHz. In this embodiment, for the specific descriptions of the above preset differences, algorithm parameters, and step values, reference can also be made to the descriptions in the following embodiments.

[0085] In one embodiment, after step S308, it further includes: S310, obtain the current vibration frequency of the ultrasonic nebulizer and store it as the second target frequency. In this embodiment, for the purpose of storing the second target frequency, reference can be made to the descriptions in the following embodiments.

[0086] In this embodiment, through two judgments and adjustments, the ultrasonic atomization sheet of the ultrasonic nebulizer can work at the required vibration frequency. In order to further describe the solution of this application in more detail, please refer to the following embodiment with three adjustments using three differences:

[0087] Please refer to Figure 4, in one embodiment, step S300 of the above is further optimized to provide another control method for an atomization device. Step S300 includes steps S304, S305, S306, S307, S308, S309, S310, and S311. Among them, step S304 is a further optimization step of step S301; steps S305, S307, and S309 are further optimization steps of step S302; steps S306, S308, S310, and S311 are further optimization steps of step S303, specifically as follows:

[0088] S304, set a first preset difference, a second preset difference, and a third preset difference that decrease in sequence, as well as corresponding first preset algorithm parameters, second preset algorithm parameters, and third preset algorithm parameters, and a first preset step value, a second preset step value, and a third preset step value that decrease in sequence;

[0095] S311, lock the vibration frequency of the ultrasonic atomizer as the first target frequency, so that the ultrasonic atomizer operates at the first target frequency.

[0096] In step S304 of this embodiment, first, according to the distance between the vibration frequency reflected by the previously calculated difference and the target vibration frequency, the three preset differences are used to divide this distance, so as to facilitate subsequent hierarchical or step-by-step adjustment, and the speed, range, and number of adjustments can be controlled during the process of adjusting the vibration frequency, improving the accuracy of adjustment and ensuring the stability of the ultrasonic nebulizer. It should also be noted that step S304 in this embodiment is not limited to being the first execution step of step S300. Step S304 in this embodiment can be executed synchronously during the execution of subsequent steps S305 to S310.

[0097] In step S305 of this embodiment, if the judgment is yes, the adjustment method of step S306 is executed at this time. In one execution step, it can be to end the step after executing step S306 and wait for the next startup. If the judgment in step S305 is no, that is, step S307 is executed. In step S307 of this embodiment, if the judgment is yes, the adjustment method of step S308 is executed at this time. In one execution step, it can be to end the step after executing step S308 and wait for the next startup.

[0098] If the judgment in step S307 is no, that is, step S309 is executed. In step S309 of this embodiment, if the judgment is yes, the adjustment method of step S310 is executed at this time. In one execution step, it can be to end the step after executing step S310 and wait for the next startup.

[0099] If the judgment in step S309 is no, the adjustment method in step S311 is executed, that is, in step S309, after executing the previous steps S305 and S307, at this time, the vibration frequency of the ultrasonic nebulizer has stepped towards the target vibration frequency at least twice, and the third preset difference is already the minimum gap to reach the target vibration frequency. When entering step S309 at this time, if the vibration frequency is less than the third preset difference, it can be judged that the current vibration frequency has reached the value of the target vibration frequency or is within the range required by the target vibration frequency, that is, the error is small enough at this time, and it can be judged that the current vibration frequency has reached the optimal frequency. Therefore, step S311 can be executed to lock the current vibration frequency of the ultrasonic nebulizer as the first target frequency and perform atomization at this first target frequency. That is, in this embodiment, the first target frequency is stored as the optimal frequency for subsequent judgment and adjustment.

[0100] Further explanation is made on the first target frequency in step S311 of this embodiment. In this embodiment, storing the first target frequency enables the ultrasonic nebulizer to directly adjust the vibration frequency according to the first target frequency in subsequent operations, set the vibration frequency directly to the correct target frequency, and reduce the number of frequency conversions. In this embodiment, storing the first target frequency may also mean that when the next operation is started, the ultrasonic nebulizer directly uses the first target frequency as the starting frequency for operation and then performs the above adjustment steps in real time according to the first target frequency. This setting takes into account that after the ultrasonic nebulizer is used multiple times, the actual target vibration frequency may change due to internal structure loss or aging. At this time, the ultrasonic nebulizer can still perform the above adjustment steps based on the first target frequency obtained previously and make adaptive adjustments in real time to match the equally flexible target vibration frequency.

[0101] In one example, the first target frequency is the above-mentioned optimal frequency. In another example, the first target frequency is the maximum frequency at which the ultrasonic nebulizer operates. It should also be noted that in this embodiment, the sorting of multiple preset differences is very necessary, which can control the adjustment span and direction of the vibration frequency during the adjustment process, so that the vibration frequency steadily changes towards the required target vibration frequency.

[0102] Please refer to Figure 4 , in one embodiment, the control method is further optimized. Specifically, after step S310, that is, after updating the algorithm parameters to the third preset algorithm parameters and adjusting the vibration frequency of the ultrasonic nebulizer step by step with the third preset step value, it further includes:

[0103] S312, obtaining the current vibration frequency of the ultrasonic nebulizer and storing it as the second target frequency.

[0104] In this embodiment, the second target frequency in step S312 is the storage step after executing step S10, and its purpose is to obtain another secondary target vibration frequency in this application. In one embodiment, the second target frequency is the sub-optimal frequency. Obtaining and storing the second target frequency obtained after the last adjustment step can also be used to adjust the vibration frequency of the ultrasonic nebulizer when it is started for the next time. Therefore, in this application, after executing the above steps, the vibration frequency after the next start of the nebulizer can be directly adjusted through the obtained first target frequency and second target frequency, thereby optimizing the subsequent adjustment method and improving the efficiency of atomization frequency sweeping and frequency locking.

[0105] In one embodiment, the ranges of the above-mentioned preset difference, preset algorithm parameters, and preset step value are further optimized as follows: set the first preset difference to be between 0.8 - 1.5 W, the second preset difference to be between 0.4 - 0.7 W, and the third preset difference to be between 0.1 - 0.3 W; the first preset algorithm parameters are Q ∈ [0.4, 0.7], R ∈ [0.5, 3], the second preset algorithm parameters are Q ∈ [0.08, 0.3], R ∈ [4, 10], and the third preset algorithm parameters are Q ∈ [0.01, 0.07], R ∈ [15, 30], where Q is the process noise and R is the measurement noise; the first preset step value is between ±9 - 12 kHz, the second preset step value is between ±6 - 8.5 kHz, and the third preset step value is between ±2 - 5 kHz.

[0106] In this embodiment, W is the unit watt of real-time power, abbreviated as "Watt" or "W" for short. kHz is the unit kilohertz of frequency, abbreviated as "kilohertz" or "kHz" for short.

[0107] In one embodiment, the ranges of the above-mentioned preset difference, preset algorithm parameters, and preset step value are further optimized as follows: set the first preset difference to be 0.8 W, the second preset difference to be 0.4 W, and the third preset difference to be 0.1 W; the first preset algorithm parameters are Q = 0.4, R = 0.5, the second preset algorithm parameters are Q = 0.08, R = 4, and the third preset algorithm parameters are Q = 0.01, R = 15, where Q is the process noise and R is the measurement noise; the first preset step value is ±9 kHz, the second preset step value is ±6 kHz, and the third preset step value is ±2 kHz.

[0108] In another embodiment, the ranges of the above-mentioned preset difference, preset algorithm parameters, and preset step value are further optimized as follows: set the first preset difference to be 1.5 W, the second preset difference to be 0.7 W, and the third preset difference to be 0.3 W; the first preset algorithm parameters are Q = 0.7, R = 3, the second preset algorithm parameters are Q = 0.3, R = 10, and the third preset algorithm parameters are Q = 0.07, R = 30, where Q is the process noise and R is the measurement noise; the first preset step value is ±12 kHz, the second preset step value is ±6 kHz, and the third preset step value is ±5 kHz.

[0109] In yet another embodiment, please refer to Figure 5In the steps, the ranges of the above preset difference, preset algorithm parameters, and preset step values can be further optimized as follows: set the first preset difference to 1.0W, the second preset difference to 0.6W, and the third preset difference to 0.2W; the first preset algorithm parameters are Q = 0.5, R = 1, the second preset algorithm parameters are Q = 0.1, R = 5, and the third preset algorithm parameters are 0.02, R = 25, where Q is the process noise and R is the measurement noise; the first preset step value is ±10kHz, the second preset step value is ±8kHz, and the third preset step value is ±4kHz.

[0110] Similarly, after step S310 of the above specific embodiment, step S312 can be further executed to obtain the current vibration frequency of the ultrasonic nebulizer and store it as the second target frequency, so that when the ultrasonic nebulizer is started again for work subsequently, judgment and adjustment are performed based on the above first target frequency and second target frequency.

[0111] Please refer to Figure 6 and Figure 7 , in an embodiment, the control method of the present application is further optimized. After step S13, that is, after calculating the real-time power according to the updated working parameters, it further includes:

[0112] S14, determining whether the real-time power is greater than the maximum power; if so, executing step S15, if not, executing step S16;

[0113] S15, the heating nebulizer stops working and an over-power alarm is given;

[0114] S16, determining whether the vibration frequency of the ultrasonic nebulizer reaches the first target frequency; if so, executing step S17, if not, executing step S20;

[0115] S17, locking the vibration frequency and working at the first target frequency;

[0116] S20, continuing to calculate the difference between the real-time power and the preset power.

[0117] In steps S14 and S15 of this embodiment, first, the real-time power currently calculated in the heating nebulizer is judged. When the real-time power is greater than the preset power, it is judged that the current heating nebulizer system is in an abnormal working state, and the heating nebulizer is stopped in time and an over-power alarm is given to ensure the stability and safety of the heating nebulizer during operation and avoid damage caused by over-power operation of the heating nebulizer.

[0118] In step S16 of this embodiment, first, the vibration frequency of the ultrasonic nebulizer is judged to determine whether it has reached a preset first target frequency. If the judgment result is yes, it means that the ultrasonic nebulizer has reached the required target frequency, so there is no need to adjust and track the frequency anymore. Therefore, the frequency is directly locked for execution, that is, step S17 is executed, and step S20 does not need to be executed. If it does not reach the target frequency, that is, step S20 and subsequent steps are continued to perform the frequency tracking work. Thus, it is possible to avoid the ultrasonic nebulizer from performing ineffective frequency tracking work.

[0119] In summary, the process provided by the above embodiment aims to improve the adaptability of the system to the real-time power target by dynamically adjusting the parameters of the Kalman filter and the scanning range. In the case of rapid changes, the adjustment intensity is greater; while when the distance from the optimal power is small, the adjustment range is reduced, and finally the optimal frequency is locked.

[0120] Please refer to Figure 8 , in one embodiment, the control method of the present application is further optimized. After step S312 is executed, that is, after being stored as the second target frequency, it further includes:

[0121] S40, detecting the air flow inside the atomization device;

[0122] S41, judging whether there is a first target frequency; if yes, step S42 is executed, if not, step S43 is continued to be executed;

[0123] S42, the ultrasonic nebulizer starts atomization work at the first target frequency;

[0124] S43, judging whether there is a second target frequency; if yes, step S44 is executed, if not, step S45 is executed;

[0125] S44, the ultrasonic nebulizer starts atomization work at the second target frequency;

[0126] S45, the ultrasonic nebulizer starts atomization work at the vibration frequency adjusted last time.

[0127] In this embodiment, an improvement is made to the adjustment method when the atomizer is restarted after undergoing the above steps. In step S40 of this embodiment, the air flow inside the atomization device is detected, that is, it is detected whether there is an action of the user sucking the atomization matrix in the atomization device at this time, and it is judged whether to start the atomization device. In one example, the atomization matrix is e-liquid. In step S41 of this embodiment, since when the atomization device is restarted, it has passed through the judgment steps of the foregoing embodiments and may have obtained the first target frequency and the second target frequency, therefore, when restarting, it can be directly judged whether the vibration frequency when working again reaches the first target frequency to judge whether the vibration frequency of the ultrasonic atomizer needs to be adjusted again, thereby helping to quickly judge whether the vibration frequency of the ultrasonic atomizer reaches the required standard and being able to reduce the number of frequency sweeping and frequency chasing times. When the first target frequency is stored, there is no need to continue to judge whether there is a second target frequency. In step S43 of this embodiment, at this time, since no record of the first target frequency is obtained, further, it is checked whether there is a record of the second target frequency. If there is, then the ultrasonic atomizer does not need to perform multiple frequency sweeping and frequency chasing at this time, and can directly work at the second target frequency that is relatively close to the target vibration frequency. However, in fact, there is also a situation where neither the first target frequency nor the second target frequency is obtained. For example, when the above step S306 or step S308 is executed, the adjustment process ends. That is, the judgment of all preset differences is not completed. At this time, the vibration frequency recorded by the atomizer is the vibration frequency of the previous adjustment. Therefore, step S45 can be directly executed to work with the result of the previous frequency modulation. And when judging whether to perform frequency sweeping and frequency chasing again in the subsequent process, since the vibration frequency of the previous adjustment is used for stepping, the number of frequency sweeping and frequency locking can also be reduced. In this embodiment, the first target frequency is the optimal frequency, and the second target frequency is the sub-optimal frequency.

[0128] Please refer to Figure 8 , after the above steps S42, S44, and S45, it further includes step S50:

[0129] S50, the ultrasonic atomizer performs atomization work.

[0130] In this embodiment, after the ultrasonic atomizer determines at which frequency to start the atomization work, all steps are summarized in step S50, indicating that the ultrasonic atomizer has performed the atomization work of the ultrasonic atomization sheet.

[0131] Please refer to Figure 9 , in one embodiment, the control method of the present application is further optimized. After step S50, that is, after the ultrasonic atomizer performs atomization work, it further includes:

[0132] S51, Determine whether the duration of ultrasonic atomization operation has reached a preset duration; if so, execute step S52, if not, execute step S53;

[0133] S52, Control the screen locking operation of the ultrasonic nebulizer;

[0134] S53, If not, continue the atomization operation until the duration of the atomization operation reaches the preset duration.

[0135] In step S51 of this embodiment, a timing logic is added to monitor the duration of the atomization operation of the ultrasonic atomization sheet of the ultrasonic nebulizer. In step S52 of this embodiment, the screen locking operation of the ultrasonic nebulizer aims to ensure the safety of the ultrasonic nebulizer or achieve an energy-saving effect. In step S53 of this embodiment, continue to ensure that the duration of the atomization operation of the ultrasonic nebulizer reaches the required duration to ensure the atomization effect.

[0136] In one embodiment, the above-mentioned preset duration is 15 - 25s. In another embodiment, the above-mentioned preset duration is 20s.
